Separately, regarding US economic data, PPI will be released at
8:30 a.m. ET.

As for the rest of the world, here's the scoreboard as of 7:28
a.m. ET:

The British pound is down by 0.7% at
1.2132 against the dollar
after UK parliament passed the so-called Brexit bill
without any amendments on Monday night. This paves the way for
prime minister Theresa May to trigger Article 50 at
some point this month. The pound's dip on
Tuesday "suggests
that the reality of the UK’s divorce from Europe and two years
of horse-trading to agree trade deals is beginning to spook the
FX market," Kathleen Brooks of City Index writes in her Tuesday
morning email.

The Russian ruble is down by 0.5% at
59.1016 per dollar, while Brent crude oil, the international
benchmark, is up by 0.7% at $51.70 per barrel. On Monday, a BMI
Research team argued in a note to clients that the ruble "is set
for a period of short-term weakness due to falling oil prices and
waning optimism over the prospect of warming US-Russia relations.
That said, high and rising real interest rates in Russia will
limit the impact of oil price volatility on the unit, and we
expect the ruble to outperform Brent."

The euro is down by 0.2% at 1.0634
against the dollar. Earlier, the German ZEW economic sentiment
index came in at 12.8 for March, below expectations of 13.1, but
above the prior reading of 10.4. As for the eurozone's ZEW
economic sentiment, it clocked in at 25.6, above expectations of
19.3, and above the prior reading of 17.1.
